Stanford researchers make ammonia from air and water microdroplets

Green Car Congress

Stanford researchers, with a colleague from King Fahd University of Petroleum and Minerals, have developed a simple and environmentally sound way to make ammonia with tiny droplets of water and nitrogen from the air. Water microdroplets are the hydrogen source for N 2 in contact with Fe 3 O 4. The conversion rate reaches 32.9 ± 1.38

Researchers develop highly efficient organometal halide perovskite photoelectrodes for water splitting

Green Car Congress

Photoelectrochemical (PEC) water splitting based on solar energy is one promising approach for the production of green hydrogen. However, its widespread application is limited by a lack of efficient photoanodes for catalyzing the rate-limiting oxygen evolution reaction (OER), an important reaction in PEC water splitting. 202300951

UT El Paso-led team designs cactus-inspired low-cost, efficient water-splitting catalyst

Green Car Congress

Researchers led by engineers at The University of Texas at El Paso (UTEP) have proposed a low-cost, cactus-inspired nickel-based material to help split water more cheaply and efficiently. who led the study. who led the study. Nickel, however, is not as quick and effective at breaking down water into hydrogen.

Study finds the wettability of porous electrode surfaces is key to making efficient water-splitting or carbon-capturing systems

Green Car Congress

As water-splitting technologies improve, often using porous electrode materials to provide greater surface areas for electrochemical reactions, their efficiency is often limited by the formation of bubbles that can block or clog the reactive surfaces. As a result, there were substantial changes of the transport overpotential.

New stable water-splitting catalyst doesn’t require expensive iridium

Green Car Congress

Researchers have developed a nickel-stabilized, ruthenium dioxide (Ni-RuO 2 ) anode catalyst for proton exchange membrane (PEM) water electrolysis. The Ni-RuO 2 catalyst shows high activity and durability in acidic OER for PEM water electrolysis. Illustration by Zhen-Yu Wu. 2 , suggesting potential for practical applications.
